While one might think that there is no apparent connection between soil erosion and droughts, there actually are connections.

The leading cause of soil erosion is vegetation loss as a result of over-grazing, over-cultivation (improper farming techniques), and natural causes such as forest and pasture fires. http://www.botany.uwc.ac.za/Envfacts/facts/erosion.htm

The two main erosional mechanisms are wind and water. Vegetation increase the permeability of soil and as such its ability to transmit surface and rain water to groundwater (aquifer) systems through root systems and the organic matter in the upper soil horizons. When this vegetation is removed, the soil becomes compacted, less permeable, and hotter. If or when it rains, runoff is increased and the water can no longer replenish the aquifers.

When the good soil goes away, the plants go away, when the plants go away, there's no more ground cover, and in the summer, the water all evaporates out of the ground...then you get this dry, cracked-clay looking thing going on, and the little kid from children's christian fund steps in front of the camera, and begs for money...
